Can anyone recommend a good substrate for a clam tank? I want to set up a small cube tank that is 24"x24"x12" tall. I will be using a single halide pendant for lighting. Is oolite too fine or should I use a bigger grain. I have like 25lbs. or so of small grain coral sand sitting in my garage. I probably could use that stuff for a calcium reactor though. Thanks.
